Anomalies of the appendix are extremely rare, and a horseshoe appendix is even rarer. A literature search has revealed only five reported cases. In this report, we present a case of a horseshoe appendix.A 78-year-old man was referred for further examination following a positive fecal occult blood test. A mass in his ascending colon was detected on colonoscopy, while computed tomography showed that it was connected to the appendix. Tumor invasion derived from the ascending colon or appendix was suspected. We diagnosed ascending colon cancer prior to laparoscopic ileocecal resection...

Cancer of uterine cervix is one of the most common malignancies in women. Metastatic recurrence of cervical cancer in spleen is rare, mostly seen in autopsies. Splenic metastasis from cervical cancer in a living patient without disseminated metastases is rarer. Here, we present the case of a lady aged 46 years with cervical cancer-squamous cell carcinoma-who had undergone radical hysterectomy and postoperative 50 Gy of intensity modulated radiation therapy in 25 fractions and 50 mg of weekly cisplatin for 6 weeks...

BACKGROUND: It can be difficult to locate the superior mesenteric vein and dissect around middle colic vessels during laparoscopic right hemicolectomy with complete mesocolon excision due to a high rate of vascular variations in the superior mesenteric vessels. Therefore, we report a modified technique for hand-assisted laparoscopic right hemicolectomy with complete mesocolic excision and central vascular ligation, which addresses these two problems. METHODS: Thirty-one consecutive patients with right colon cancer underwent this procedure from March 2014 to August 2015...

Angiogenesis, defined as the growth of new blood vessels from existing ones, plays a key role in development, growth, and tissue repair. Its necessary role in tumor growth and metastasis has led to the creation of a new category of anti-angiogenic cancer therapies. Preclinical development and evaluation of potential drug candidates require models that mimic real microvascular networks. Here, we describe the rat mesentery culture model as a simple ex vivo assay that offers time-lapse imaging of intact microvascular network remodeling and demonstrate its application for anti-angiogenic drug testing...

4T1 metastatic breast cancer model have been widely used to study stage IV human breast cancer. However, the frequent inoculation of a large number of cells, gives rise to fast growing tumors, as well as to a surprisingly low metastatic take rate. The present work aimed at establishing the conditions enabling high metastatic take rate of the triple-negative murine 4T1 syngeneic breast cancer model. An 87% 4T1 tumor incidence was observed when as few as 500 cancer cells were implanted. 4T1 cancer cells colonized primarily the lungs with 100% efficiency, and distant lesions were also commonly identified in the mesentery and pancreas...

Anatomy is the foundation of surgical techniques. With the development of surgery, anatomy also divided into traditional anatomy, surgical anatomy and embryonic development anatomy. Complete mesocolic excision (CME) is one of classic radical operation for colon cancer, based on the modern anatomy. CME advocates correct operation plane, and describes the mobilization and separation of the colon together with the entire regional mesocolon. With the evolution of anatomy, the definition and content of CME-related anatomic landmarks such as mesentery, fascia and space have been changed...

Surgical or local anatomy consists of two components conventionally, organs and their blood supply. In fact, they are enveloped by the fascia membrane and serous membrane. This is the third component in surgical or local anatomy, which is omitted by surgeons for many years. The omitted reasons are failed recognition and unknown function. Re-understanding of the third component in surgical or local anatomy will make some changes in the local anatomy, tumor pathology, oncology surgery and operations. Firstly, the third component makes surgical anatomy developed from organ anatomy, blood vessel anatomy to membrane anatomy, which consists of the mesentery in broad sense and its bed, both include serous membrane and fascia membrane...

Focused pathological attention to tumor invasion of the retroperitoneal resection margin after pancreaticoduodenectomy for cancer of head of the pancreas led to the knowledge of strong tendency of cancer cells to infiltrate into the retropancreatic tissue and to spread along the peripancreatic neural plexuses as the cause of local recurrence. The term 'mesopancreas' was coined to describe perineural lymphatic layer located dorsally to the pancreas and it was suggested that its complete resection will minimize loco-regional recurrence and improve outcome...

PURPOSE: Adrenal cortical carcinoma is a rare cancer that often presents in an advanced stage. Not only systemic metastases but also local recurrence and peritoneal metastases prevent long-term survival in these patients. METHODS: A profoundly symptomatic patient with extensive peritoneal metastases and local recurrence was treated using cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with melphalan as the chemotherapy agent. RESULTS: Relative sparing of the small bowel within the abdomen and pelvis allowed a visible complete resection of all cancer...

Classic colon cancer surgery refers to a wide resection of the tumor-bearing segment and the lymphatics draining along the named artery. The concept of TME has been applied to colon cancer and complete mesocolic excision (CME) in conjuction with central vascular ligation (CVL) has been introduced as the surgical treatment for colon cancer. Here, we discuss appropriate CME procedure with regard to the oncologic backgrounds, essential components, applied anatomy, laparoscopic technique, short-term, and oncologic outcomes...

Positron emission tomography/computed tomography (PET/CT) is a credible diagnostic modality for detecting primary and metastatic malignancy. PET/CT sometimes shows false positives and negatives, which make clinical diagnosis difficult. A 42-year-old man who had undergone right upper lobectomy for lung cancer 1 year previously had PET/CT for a metastatic survey of the lung. The lung cancer was stage IB (pT2N0M0) bronchioloalveolar carcinoma. PET/CT showed massive (18)F-fluorodeoxyglucose (FDG) uptake in the mesenteric lymph nodes...

BACKGROUND: Extramural venous invasion (EMVI) is defined histologically as the active invasion of tumor cells to the lumens of mesenteric vessels beyond the muscularis propria in advanced gastrointestinal cancer, resulting in distant metastases. PURPOSE: To determine the association between synchronous metastatic disease in patients with T4 gastric cancer and EMVI detected on contrast-enhanced multiple-row detector computed tomography (MDCT). MATERIAL AND METHODS: A total of 152 patients with T4 gastric carcinoma were retrospectively reviewed and divided into EMVI-positive and EMVI-negative groups where EMVI, as detected on MDCT, was defined as a tubular or nodular soft tissue thickening extending from the tumor along the vessels of the mesentery...

PURPOSE: The present study evaluated the safety and feasibility of this caudal-to-cranial laparoscopic dissection approach for the curative resection of right-sided colon cancer. To the best of our knowledge, no study has reported the caudal-to-cranial approach in the laparoscopic right colectomy with curative intent for colon cancer. METHOD: The key procedure of the caudal-to-cranial approach is the commencement of the dissection at the mesentery root, thus entering into the Toldt's space before the mesenteric vessels are accessed...

Cancer therapy-induced complications in the bowel and mesentery are fairly common. It is important for clinicians to be aware of these complications and the agents most frequently implicated. Cancer therapy is rapidly evolving and often encompasses both classic cytotoxic drugs and newer molecular targeted agents. Drugs from both broad classes can have numerous adverse effects on the bowel and mesentery that can be detected on imaging. These adverse effects include ileus, various forms of enterocolitis, gastrointestinal perforation, pneumatosis intestinalis, secretory diarrhea, and sclerosing mesenteritis...

We report a rare case of ectopic pancreatic cancer in the mesentery of the jejunum. A 68-year-old man presented with left abdominal pain. Contrast-enhanced abdominal CT revealed a 3-cm tumor in the mesentery near the ligament of Treitz. He had required surgery for gastric cancer 28 years ago;therefore, surgery was scheduled on the suspicion of recurrence/metastasis of gastric cancer or gastrointestinal stromal tumor (GIST) and mesenteric tumors. A tumor was observed in the mesentery of the jejunum of the ligament of Treitz...
